PURPOSE:To enable copying in unmagnification, reduction, magnification, etc. with exactly the same operations as ordinary copying operations in unmagnification, by using a universal cassette which can contain various sizes of copying paper with the same feed cassette and switching means disposed therein. CONSTITUTION:A regulating member 41 which regulates the width of copying paper 40 is mounted in a universal cassette 12 freely adjustably in movement in the direction intersecting orthogonally with a paper feed direction. When an operating piece 46 moving relatively with the member 41 displaces according to the selection of copying for unmagnification and reduction, unmagnification and magnification or reduction and magnification in the stage of setting the paper 40, either one of the switches SW1 and SW2 in a receiving part 11 for the above-mentioned cassette disposed in the positions corresponding to the displacing positions of the piece 46 is actuated so as to be controlled to the moving speed of an original plate and the correct position of an optical device suited for one magnification selected among the magnification, reduction, and magnification. The copying stage at the intended variable power is accomplished when the copying operations are performed in the above-mentioned state. |
